continually posting and re-posting the article for which you yourself are the author doesnt really move the needle.
nobody doubts that SOS (d) does drive increase costs.
but you are like the Scots squabbling for the scraps from Longshank's table.
by FAR, the biggest cost is private insurance. they take 1/3 right off the top. and the only function is to administer plans that CMS puts out the rules for. it is simply an added cost. i understand that we dont want to increase the size or power of the gvt, but in this case the only thing that blue cross, united, and cigna do is make things cost more. those administrators and CEOs are raping the system. its not the HOPD doc seeing medicaid patients. its not the hospital administrator or MBA (although they are a smaller problem as well).
what you will get if you make payments site-neutral is that everyone will get paid at medicaid rates (or worse).
best option is to eliminate private coverage as we know it. every citizen gets a really crappy, preventative-based, medicaid-like coverage. then, if you have the means, you buy the cadillac plan. the key to this is that the plan for everyone needs to be really sh$tty and cheap b/c we (the taxpayers) will be paying for it.
